`To all Iwhom it may concern Beit `known that we, `JUDsoN ADAMS and WARREN A. ToLMAN, of Richmond, in the county of Wayne and State of Indiana, have invented anew and Improved Bobbin-Wind- I ing Machine; and we" do hereby declare that the following is a full,I clemar, and exact description` thereof, which will enable others i skilled in the art to make and use the same, reference being had to the accompanying drawing formingfpartof this specification.

This invention relates to improvements in machinery forwindingbobbins, and it con sists in certain combinations 'and arrangements of devices with the feller-wire or guide andthe driving mechanism for the band-cylinders, so that under one adjustment the yarn may be wound in the required conical form g upon cylindrical bobbins,` and by another it may be Wound upon the bobbins having the conical bases. i i I .j Figure 1 is aplan view of a bob bin-winding machine constructed according to our improvements. ,Figa 2 is a front view of part of the machine and a sectional elevation of another part, thelatter being on the line .frl a: of Fig. 1.^ Fig. 3 is a sectional felevation taken on the line y yof` Fig. l; and Fig. 4 is also a section on the line y y, but looking in g the direction opposite to that of Fig. 3.

Similar letters of reference indicate corre-` sponding parts. f

The winding-spindles A, friction-rollers B,

Vspool-rack C, spindle-driving cylinder-D, and

yarn guide or faller E are of the ordinary construction. The faller-wire, `or one of thelsupporting-arms thereof, is connected by the rod F to the arm Gr, which is pivoted on the cyl- `inder-shaft H so that` it may rise and fall to work the said faller-guide. yAlongside this armG, and pivoted also to the shaft H so that `it may vibrate ina vertical plane, is a frame,

I,for supporting the Working-gears which opimpart the motion tothe said arm, which has a projection, N,\for `bearing on the cam. This cam isworked by means of the large cog-wheel .M on the shaftIz, the` intermediate wheelN' `mounted on a stud on the frame I, and the PATENT OFFICE.

`IMPROVEMENT IN MACHINES FoR WINDING .BoBB|Ns.,

Specification forming part of Letters Patent No. 115,264, dated May 30, 1871; antedated May 19, 1871.

i borne on frame I. Said cam is provided with a toothed hub, It, to be engaged and held as required by a sliding toothed collar, S, also on the shaft, andl keyed to it so as to turn with it, and worked by a shifting-lever, T. This shaft Q is geared with shaft L by two pairs, 'U and V, of worm-wheels, and a shaft, W, so as to have a slow motion to raise the faller-wire along the bobbin from bottom to top while the bobbin is being wound, said raising being effected by the working of the cam P against an arm,-X, projecting from the frame of the machine. The large wheel M carries a small cam,

Y, which acts (when the frame I is down at the lowest position) on the lever Z, at each revolution, at the time when the cam K has allowed the arm G to fall, and causes said lever to lift the lever Gr a short distance, through the medium of the bar Z1, and let it fall again.

-This lever Z is pivoted to the frame at Z3 on a pivot capable of adjustment, so that the lever may be moved out of reach of the cam Y when required, which is done when winding the yarn on bobbins having the conical bases, in which case it is not needed. The arm K is also to be Amade adjustable on the frame for regulating ical form, the cam K, arm Gr, and rod F moving the faller for guiding the yarn in winding the cone, while the cam P causes the frame to gradually rise and the faller to move from bottomto top of the bobbins to wind the successive layers higher thereon. When the yarn is to be Wound on the bobbins not having the conical base for beginning the winding on, the lever Z is adjusted so as to be acted upon by the cam Y, and the faller is thereby caused to have another rising-and-falling motion between each motion caused by cam K, but not so great, by which a conical base is built up at the bottom of the bobbin, as Will be clearly understood by inspection ofthe drawing. This motion so imparted to the faller-moving arm G, and thereby to the faller, by means of the ca1nY,lever Z, and bar Z1,bei;ng,` only required while the base is forming, is made to cease by the raising of the frame l and arm Gr by the cam P, which is so adjusted that the cam Y will be out of reach of the arm Z by the time the base is properly formed. The taller-Wire arm is connected to the rod F, so as to be readily detached for dropping it out of the Way when the completed bobbins are to be removed;

After the bobbins are completed the camwheel P is again shifted back, as above stated, to let the frame I and the taller down to the place of beginning.

Having thus described our invention, We claim as new and desire to secure by Letters Patent- 1. The combination,'With the driving-shaft H, the arm X, and the faller-guide, of the arm G and frame I pivoted on the said shaft, and the cams K and P mounted on the said frame and geared together and With the shaft, in the manner substantially as specified.

2. The combination, With taller-guide, moving-arm G, and its operating mechanism, of the lever Z, cam Y, and slide-bar Z1, all arranged for operation substantially as specified.
